Аннотация: A special group of substances that are very dangerous for the biosphere includes war gases such as mustard gas (bis(2-chloroethyl)sulphide). The influence of mustard gas hydrolysis products (MGHPs) on soil microbiota has been investigated. These substances bear numerous toxic effects on soil microorganisms. They change significantly the number and the specific composition of soil microbiota and inhibit the enzyme activity of soils. The main "ecological targets" of mustard and its hydrolysis products' toxic action have been determined. MGHPs affect the growth and reproduction of soil micromycetes, as well as their morphological and cultural properties. Increase in number and size of mitochondria in the fungal cells is accompanied by increase in dehydrogenases activity. Cell permeability influenced by MGHPs grows in connection with concentration of toxicants. Increase of permeability corresponds to growth of the amount of unsaturated fatty acids. The changes in the fatty acid composition of lipids in the cells of the soil micromycetes display their adaptation to adverse impact of the substances studied. MGHPs and thiodiglycol enhance synthesis of polysaccharides and pigments.

Reactions of the latter with excess morpholine result in replacement of two fluorine atoms in positions 5 and 7 by the amine residues.

Аннотация: Novel pharmacologically active silicon—titanium—zinc- and silicon—titanium—boron-containing glycerohydrogels were synthesized by the sol—gel method using silicon, titanium, zinc, and boron glycerolates as biocompatible precursors. The compositions and structural features of the hydrogels were studied by transmission electron microscopy, scanning electron microscopy, IR spectroscopy, atomic emission spectrometry, and elemental analysis methods. The disperse phase and liquid water—glycerol medium of the hydrogels were isolated by cold exhaustive extraction with ethanol and characterized. The 3D polymeric network of the gels is formed by the products of hydrolysis and subsequent (co)condensation of silicon-/silicon—boron-containing precursors. Titanium and zinc glycerolates undergo no hydrolytic transformations under gelation conditions and exist in the cells of the 3D polymeric network in the form of amorphous nanoparticles that are not linked to the network by covalent bonds. Models of the structures were proposed. The gels are characterized by antimicrobial activity, which is more pronounced for the silicon—titanium—boron-containing gel, and they can be considered as promising drugs for topical treatment prepared by the simple, environmentally friendly, and cost-effective method.

Аннотация: On the basis of the results obtained from NMR spectroscopy, X-ray analysis and chemical transformations, it was established that acidic hydrolysis of (2S,4S)-4-arylaminoglutamates results in the formation of lactams in which ring closure occurs with the participation of the Y-amino and alfa-COOH groups; but isomeric lactams resulting from the participation of the alfa-amino and Y-COOH groups are not formed. Isomeric lactams, that is, (2S,4S)-4-arylamino-5-oxoprolines, can be easily converted in acidic medium into more stable 4-amino-1-aryl-5-oxoprolines.

Аннотация: The hybrid materials based on polysiloxane modified by amino groups have been synthesized by the sol-gel method. Aminated polysiloxane has been prepared by the copolycondensation reaction of tetraethoxysilane with gamma-aminopropyltriethoxysilane (APS-1) and through the modification of the product (APS-2) of the hydrolysis of tetraethoxysilane by gamma-aminopropyltriethoxysilane. The composition of sorbents has been confirmed by the elemental analysis and IR Fourier spectroscopy. The high degree of sorption extraction of copper(II), nickel(II), cobalt(II), zinc(II), cadmium(II), and lead(II) ions in the case of their coexistence in an ammonia-acetate buffer solution has been observed for polysiloxanes APS-2. The synthesized surface-modified materials exhibit the highest selectivity to nickel(II) and cobalt(II) ions

XEROGEL -- TITANIUM DIOXIDE -- PALLADIUM
Аннотация: We demonstrate a few-step technique for the synthesis of PdO/TiO2 and Pd/TiO2 (0.1–2.0 wt % Pd) xerogels, which comprises hydrolysis of a palladium nitrate solution in titanium tetrabutoxide in the vapor atmosphere over an aqueous acetic acid solution, drying, and calcination of the material between 800 and 870°C. According to X-ray diffraction and electron microscopy characterization results, after calcination at 800°C the xerogels contained palladium in the form of PdO particles ≤3–5 nm in size. The highly dispersed palladium(II) oxide covered the surface of the rutile crystallites and filled pores in between. Throughout the range of Pd(NO3)2 concentrations studied, the PdO particles were identical in size. In the material calcined at 870°C, palladium had the form of metallic particles ranging in diameter from 55 to 420 nm. Raising the palladium nitrate concentration in titanium tetrabutoxide was shown to increase the average size of the Pd particles.

Аннотация: A concise procedure was developed for the synthesis of silver-containing xerogels Ag(0)/TiO2 [0.23.2 wt % Ag(0)], including the dissolution of AgNO3 in tetrabutoxytitanium, hydrolysis of the solution in acetic acid–water vapors, drying, and calcining the xerogel at 600–800°C. It was found by X-ray diff raction analysis and electron microscopy that the bulk of metallic silver particles (75–90%) in the material calcined at 800°C has a size of 25–45 nm. The fraction of particles (in the form of crystal intergrowths) with a diameter of 95–115 nm rises with an increase in the AgNO3 concentration at the dissolution stage; TiO2 is present in the rutile phase. At a calcination temperature of 600°C, the dominant TiO2 phase (72%) is anatase; in this case the size of silver particles is 5–10 nm.

ANTIVIRAL DRUG -- NUCLEOTIDE ANALOGUE -- REMDESIVIR
Аннотация: Nucleotide analogues are the divergent scaffolds that are reliable potential therapeutic drugs to treat the wide range of diseases including viral infections. For instance, Remdesivir is a biologically important nucleotide analogue prodrug that can act as a key drug target for the diseases Ebola and COVID-19. Remdesivir is a structurally chiral aryloxy-phosphoramidate prodrug as it is metabolized into nucleoside triphosphate (active drug form) inside the cell through sequential reactions by ester mediated-hydrolysis. Thus, the current minireview focuses on the earlier reported synthetic approaches of key fragments of remdesivir and their developments to attain the scale-up yields of the drug for clinical/commercial applies. Further, this review serves as a template for the design and development of other complex organic molecules.

In the case of copper(II) complexes, the hydrolysis of ester fragment occurred to form heteroligand complexes of trifluorosalicylic acid and bipyridine-like ligand associated with fluorinated alcohol. The structure of complexes corresponded to [Cu(L3-H2)(bipy or phen)*(HFIP), L3 −trifluorosalicylic acid]. In contrast, cobalt(II) complexes in refluxing HFIP resulted in the complexes [Co(L1-H)2(bipy or phen)*(HFIP), L1 – methyl trifluorosalicylate], in which the ester ligand was preserved.
